5.4 Setting the mode, connection/disconnection of terminating resistors
Setting of the operating mode and the connection/dis-
connection of the terminating resistors is done with the
DIP switches. These are on the front side of the OZD
Profi G12DU ATEX 1 (see figure 19).
Note
:
For OZD Profi G12DK ATEX 1 and OZD Profi G12DE
ATEX 1 the DIP switches are accessible after removing
the cover.
Note:
The DIP switches
S5 and S6
are without functions.
5.4.1 Setting the mode
Kindly note:
If the operating voltage for the repeater is already applied
e.g for subsequent reconfiguration, then the operating
voltage must be switched off for setting the operating
mode.
With the DIP switch
S0
the
operating mode
of the
electrical channel
CH1
is set.
With the DIP switch
S1 and S2
the
operating mode
of
the optical channel
CH2
is set.
With the DIP switch
S3 and S4
the
operating mode
of
the optical channel
CH3
is set.
With the DIP switch
S7
the internal
terminating resis-
tors
are connected and disconnected.
5.4.1.1 Setting the operating mode of the electri-
cal channel (CH1)
Operating mode “electrical channel with segment
monitoring“
CH1 is connected in this operating
mode, if S0 is in the OFF position.
Operating mode “electrical channel without
segment moni toring“
CH1 is connected in this operating
mode, if S0 is in
the ON position.
Kindly note that the operating
mode should be set only in the star
segment of the star topology.
